MANIFOLD-BOOK.

SPECIFICATION forming part of Letters Patent 1\To. 791,706, dated June 6, 1905.

Application filed March 18, 1903. Serial'No. 143,314..

To a whom, it may concern:

Be it known that I, ALEXANDER LEVISON, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new anduseful Improvements in Manifold-Books, of which the following is a specification.

My invention relates to improvements in manifold-books, the object of my invention being to provide a cheap and simple form of manifold-book by means of which triplicate copies can be obtained of any desired memand a carbon-paper 4:. Each sheet of translorations 9.

orandum, said copies being written on a blank previously prepared in triplicate.

My invention therefore resides in the novel construction, combination, and arrangement of parts for the above ends hereinafter fully specified, and particularly pointed out in the c aim.

In the accompanying drawings, Figure l is a plan view of the manifold-book, showing the parts being prepared for writing thereon. Fig. 2 is a similar view showing the parts in the position in which the triplicate copies are being detached.

Referring to the drawings, 1 represents a suitable back, to which are bound, as shown at 2, a number of sheets 3 of transparent paper parent paper comprises a stub portion 5 and three record portions 6 7 8, said four portions being separated by three vertical lines of per- The record portions 6 7 8 have suitable printed matter 10 and blanks Whereon to inscribe the desired record. The carbon sheet is carbonized on both sides, as shown, and extends to the outer edge of the inner record portion 6. A semicircular notch 11 is formed in the record-sheets and carbonpaperin line with the line of perforations 9, which divides the first record portion 6 from the stub 5. The printed matter on the portions 6 and 8 is on the same side of the sheet, while the printed matter on the intermediate portion 7 on the opposite or reverse side of the sheet, the writing on said intermediate portion being read through the sheet in its proper place in the printed matter. It is for this purpose that the paper is made transparent. It may be more convenient in printing to do all the printing on the same side of the record-sheet; but to print the middle portion from a plate in which the type had been reversed. The method of printing the middle sheet, however, forms no part of my invention, it being only necessary that the printing on the middle portion of the sheet is to show the right way when looked at from the rear side thereof. 7 In use the record-sheet is folded back upon itself in zigzag form, as shown in Fig. 1, so

that the outer portions thereof lie on the top of the carbon. The writing is made upon the uppermost or outermost portion 8. Carbon impressions of the writing are thereby formed upon the inner portions 6 7 of the sheet from opposite sides of the carbon, the impression on the sheet 6 being identical with that written on'sheet 8, while the impression on the sheet 7 is the reverse of the writing on the sheet 8.

On account of the transparency of the paper, however, this impression can easily be read through said middle portion in its proper place in the printed matter. The sheet is then detached by tearing along the innermost line of perforations, starting with the notch 11, and

the parts of the sheet are then detached from each other.

I claim I The manifold-book comprising sheets of transparent paper, each having a stub portion and three record portions, all of said portions being separated by parallel weakened lines and adouble carbon-sheet attached to the stubs and extending from the stub portion only to the'line of division between the inner two record portions, substantially as described.

In witness whereofI have hereunto set my hand in the presence of two subscribing witnesses.

ALEXANDER LEVISON. Witnesses:
